Comparison Of Important Tools, On both sides of the Space race Options

Here are two nearly identical images. One of these was used by Sergei Korolyev, the other by Wherner von Braun. Can you tell which is which?





And here's a more interesting question -- how many of us here on UMSF have actually *used* a slide rule in their lives? I know I used a slide rule, even in a completely non-engineering field -- I'd use it to do basic scaling functions when doing layout on newspapers and such.

Since both Neil Armstrong and Buzz Aldrin took their own personal slide rules to the Moon, people were obviously using them only 35 or so years ago. So, how many of us have ever used one?

I was born in 1948 and I certainly used a slide rule back in the 60's in high school.

As I remember it I first used electronic desk calculators and minicomputers (HP1000) as an undergraduate in about 1970 or 1971, and bought my first pocket calculator (also HP, RPN (anybody remember that?)) at about the same time. It was quite expensive.

The first PC I used on my job was a Commodore PET in about 1978, and my first private PC, a Microbee Z-80 CP/M machine with 32K memory and a cassette tape recorder as "mass memory" in about 1982.

Time flies!
